Abstract

PURPOSE:To automatically pierce the hole with a rupture burr without the need for work chip treatment and to reduce a piercing cost by discharging the projecting piece for connection of the main body of the container lid received on a rotary type piercing cradle by a feeding means by piercing it with the can working press in a tapered drill shape. CONSTITUTION:The main body 20 of a container lid with the projection piece 26 for linking received in a feeding zone made upwards to the circular recessed part 56 of the cradle 10 of the main body 2 of a rotary type piercing device is supported between still guides 58 and turned to a piercing zone by rotating together with the cradle 10. In the piercing zone a lifting member 64 is descended by the roller 68 engaged with the can groove 72 of a stationary cam block 70 and piercing is executed towards a recessed part 52 by a tip 98 sharping piercing tool 94 with pressing the projecting piece 26 by a synthetic resin elastic body 100. In that case a hole is opened without the generation of a working chip. Consequently there is no need for chip processing and the automatic piercing is made efficient.
